Description

本発明は、医薬品や健康食品等に広く汎用されているシームレスカプセルに関するものであって、特に本来一つずつ個別に分離されるはずのシームレスカプセルが製造中に連結・付着してしまうことによって発生する連球不良(連球不良品)を機械的に選別し、良品から除去できるようにした新規な検出手法に係るものである。   The present invention relates to seamless capsules that are widely used for pharmaceuticals, health foods, and the like, and is particularly generated when seamless capsules that should be individually separated one by one are connected and adhered during manufacture. The present invention relates to a novel detection technique that mechanically sorts out a defective ball (a defective ball) and removes it from a non-defective product.
医薬品や健康食品等にあっては、例えば内部に薬剤や食品を収容し、その周囲を外皮で被覆したほぼ球形を成すシームレスカプセルが市場に流通している。例えば「仁丹」(森下仁丹株式会社の登録商標)もこの種のシームレスカプセルの一つである。
このようなシームレスカプセルを製造するにあたっては、例えばカプセル内に収容する内容物(薬液など)と、カプセル外皮となる外皮液とを二重ノズルから硬化液に滴下して硬化させる手法が一般に多く採用されている(いわゆる人造イクラの製造手法)。この際、当然ながら、二重ノズルにおける内側部分から薬液を流出させ、二重ノズルにおける外側部分から外皮液を流出させるものである。
そして、このような滴下に合わせて、例えば二重ノズルに振動を与えることによって、二重ノズルから放出する液体を一粒ずつの適正サイズに分離し(しずく状に垂らすことになり)、ほぼ均一な大きさのシームレスカプセルを得るものである。
In the case of pharmaceuticals, health foods, and the like, for example, seamless capsules having a substantially spherical shape in which medicines and foods are accommodated inside and covered with an outer skin are on the market. For example, “Nitan” (registered trademark of Morishita Nitan Co., Ltd.) is one of such seamless capsules.
In manufacturing such a seamless capsule, for example, a method of dripping and curing the contents (chemical solution, etc.) contained in the capsule and the capsule liquid that becomes the capsule shell from the double nozzle to the curing liquid is generally used. (So-called artificial salmon roe production method). Under the present circumstances, naturally, a chemical | medical solution flows out from the inner part in a double nozzle, and an outer skin liquid flows out from the outer part in a double nozzle.
And in accordance with such dripping, for example, by giving vibration to the double nozzle, the liquid discharged from the double nozzle is separated into appropriate sizes one by one (it will be dripped) and almost uniform A seamless capsule of a large size is obtained.
しかしながら、上記二重ノズルに加える振動の加減や液体の粘性等によっては、本来一つずつに分離されるはずのシームレスカプセル同士が連結・付着し不良品となって出現することがある(二つ連結することが多い)。ここで、特に医薬品や健康食品等の製造においては、極めて厳しい製品管理や工程管理等が要求されるため、このような「連球不良品」も完全に製品(良品)から排除することが求められている。このため、従来このようなシームレスカプセルの製造工程においては、このような連球不良品の選別検査が必須となっており、その検査は専ら作業者による目視作業(人手)によって行われていた(例えば特許文献1、2参照)。   However, depending on the vibration applied to the double nozzle and the viscosity of the liquid, the seamless capsules that should have been separated one by one may be connected and adhered to each other and appear as defective products (two Often connected). Here, especially in the manufacture of pharmaceuticals and health foods, extremely strict product management and process management are required, so it is necessary to completely eliminate such “ball games” from products (non-defective products). It has been. For this reason, conventionally, in the manufacturing process of such a seamless capsule, it is essential to sort and check such defective continuous ball, and the inspection has been performed exclusively by the visual work (manual) by the operator ( For example, see Patent Documents 1 and 2).
なお、従来、この種の目視作業は、例えば複数の作業者が適宜の数のシームレスカプセルをシャーレ等に移し取り、このシャーレを揺らしながら、その揺れ具合を見て、連球不良品の存否を判別し、不良品を発見した場合には、これをピンセットでつまんで良品から除去するという作業であった。しかしながら、このような目視による作業では、多大な時間を要し、また作業者の数が多くなるほど、検査の質が不均一となり、また各作業者によって判断基準も微妙に異なるため、完全に不良品の混入を0にすることは困難であった。このようなことから、特にシームレスカプセルを大量生産する場合には、上記作業者による目視検査ではなく、多くのシームレスカプセルを短時間で且つ正確に検査できる機械的な検査手法が新たに求められていた。   Conventionally, this type of visual operation is performed by, for example, a plurality of workers transferring an appropriate number of seamless capsules to a petri dish, etc. When it was determined that a defective product was found, it was picked up with tweezers and removed from the good product. However, such visual work requires a lot of time, and as the number of workers increases, the quality of the inspection becomes non-uniform, and the judgment criteria differ slightly from worker to worker. It was difficult to reduce the mixing of good products to zero. For this reason, there is a need for a new mechanical inspection method that can accurately inspect many seamless capsules in a short time, rather than the visual inspection by the operator, particularly when mass production of seamless capsules. It was.

これら各請求項記載の発明の構成を手段として前記課題の解決が図られる。
まず、請求項1、5記載の発明によれば、シームレスカプセルの連球不良の選別が能率的に行え、量産レベルにも対応できる。また、選別はエアによって行うため、極めて衛生的である。
The above-described problems can be solved by using the configuration of the invention described in each of the claims.
First, according to the first and fifth aspects of the invention, seamless capsules can be efficiently screened for defective continuous balls, and can cope with a mass production level. Moreover, since sorting is performed by air, it is extremely hygienic.
また、請求項2、6記載の発明によれば、連球不良品を含むシームレスカプセルを、エア接触エリアにおいてほぼ同じ姿勢で落下させるため、当該エリアを落下するシームレスカプセル(特に不良品)のエア受け面積(投影面積)が均一化し、良品の飛距離と不良品の飛距離とが安定化し、風選の選別精度が向上する。
なお、ごく一般的な風選は、検査対象物を単に自然落下させている間に、風(エア)を当てて選別することが多いが、この場合には、例えば検査対象物が部分的に塊状になって落下すること等が懸念され、その分、特にエア接触エリアでの検査対象物の落下姿勢にもバラツキが生じ易く(エアを受ける投影面積が不均一化し)、風選の精度低下(精度悪化)が懸念される。
Further, according to the inventions of claims 2 and 6, since the seamless capsule including the defective ball ball is dropped in substantially the same posture in the air contact area, the air of the seamless capsule (particularly a defective product) falling in the area. The receiving area (projected area) is made uniform, the flying distance of non-defective products and the flying distance of defective products are stabilized, and the selection accuracy of wind selection is improved.
Note that very common wind selection is often performed by applying wind (air) while the object to be inspected is naturally dropped, but in this case, for example, the object to be inspected is partially There is concern about falling in a lump, etc., and in particular, the drop posture of the test object in the air contact area is likely to vary (the projection area that receives air becomes uneven) and the accuracy of wind selection is reduced. There is concern about (accuracy deterioration).
また、請求項3記載の発明によれば、エア接触エリアにおいてシームレスカプセルの落下姿勢をほぼ同じ状態に保つ具体的手法を現実のものとする。   According to the third aspect of the present invention, a specific method for maintaining the seamless capsule dropping posture in the air contact area in substantially the same state is realized.
また、請求項4、8記載の発明によれば、飛距離の差で良品と連球不良品とを仕分けるため、短時間で且つ正確に連球不良品を検出することができる。
なお、本発明では、軽い良品よりも重い連球不良品を遠くに飛ばしており、この点が通常の風選とは大きく相違するものである(通常の風選は軽いものを遠くに飛ばして選別する)。
In addition, according to the fourth and eighth aspects of the invention, the good product and the defective ball ball are classified according to the difference in the flight distance, so that the defective ball ball can be detected accurately in a short time.
Note that in the present invention, heavier ball-joint products than light good products are thrown away, and this point is very different from normal wind selection (normal wind selection is to fly light items far away). Sorting).
また、請求項7記載の発明によれば、傾斜状態に設けた搬送軌道上にシームレスカプセルを列状に載せ(整列させ)、この搬送軌道を振動させて、軌道上のシームレスカプセルを順次、エア接触エリアに放り出すため、シームレスカプセルをほぼ一定の力と傾斜角度でエア接触エリアに分散状態で供給することができ、シームレスカプセルの落下姿勢をほぼ同じ状態に揃えることができる。   According to the seventh aspect of the present invention, the seamless capsules are placed (aligned) in a line on the transport track provided in an inclined state, and the transport track is vibrated so that the seamless capsules on the track are sequentially moved to the air. Since it is thrown out to the contact area, the seamless capsule can be supplied in a distributed state to the air contact area with a substantially constant force and inclination angle, and the falling posture of the seamless capsule can be made to be almost the same.
また、請求項9記載の発明によれば、シームレスカプセルに接触させるエアの指向をほぼ水平に補正してからシームレスカプセルに当てるため、エアの当て方(指向)がより一定化し、良品と連球不良品との飛距離の差を、更に明確に生じさせることができ、一層、風選の精度を向上させることができる。   According to the ninth aspect of the present invention, since the direction of the air to be brought into contact with the seamless capsule is corrected substantially horizontally and then applied to the seamless capsule, the air application method (direction) is made more constant, and the non-defective product and the ball The difference in the flight distance from the defective product can be more clearly generated, and the accuracy of wind selection can be further improved.
また、請求項10記載の発明によれば、良品のシームレスカプセルの形状がほぼ球形状であり、不良品はこれを連接した連珠タイプであるため、良品と連球不良品との飛距離の差をより明確に生じさせることができ、より一層、精度の高い風選を可能とする。   In addition, according to the invention of claim 10, since the shape of the non-defective seamless capsule is substantially spherical, and the defective product is a continuous bead type connecting the non-defective products, the difference in the flight distance between the good product and the defective solid ball product. Can be generated more clearly, and the wind can be selected with higher accuracy.

本発明を実施するための形態は、以下の実施例に述べるものをその一つとするとともに、更にその技術思想内において改良し得る種々の手法を含むものである。   The mode for carrying out the present invention includes one described in the following embodiments, and further includes various methods that can be improved within the technical idea.
説明にあたっては、本発明において検査対象となるシームレスカプセル1の基本構造についてまず説明した後、このシームレスカプセル1のなかから不良品(連球不良品)を選別し、除去する検出装置の一例について説明しながら、併せて検出方法について説明する。   In the description, the basic structure of the seamless capsule 1 to be inspected in the present invention will be described first, and then an example of a detection device that selects and removes defective products (ball-joint defective products) from the seamless capsule 1 will be described. However, the detection method will be described together.
まずシームレスカプセルCについて説明する。
シームレスカプセルCは、例えばカプセル内に油性の薬剤や食品を収容し、その周囲をゼラチン等の水溶性高分子(ゲル化剤)で被覆したものであり、ほぼ球形状に形成されることが多く、以下の説明でもほぼ球形状を成すシームレスカプセルCについて主に説明する。
また、シームレスカプセルCの製造にあたっては、上述したように二重ノズルから内容物となる薬液と、外皮部となる外皮液とを同時に硬化液(冷却液)に滴下して、硬化させる手法が一般に多く採用されている(いわゆる人造イクラの製造手法)。この際、当然ながら、二重ノズルにおける内側部分から薬液を送出し、二重ノズルにおける外側部分から外皮液を送出するものである。
そして、このような滴下に合わせて、例えば二重ノズルに振動を与えることによって、二重ノズルから送出される液体を一粒ずつの適正サイズに分離して行き(しずく状に垂らすことになり)、継ぎ目の無い、ほぼ均一な大きさのシームレスカプセルCを得るものである。
このようにシームレスカプセルCの基本構造は、薬液等の内容物を、継ぎ目の無い外皮部で被覆して成るものである。ここで、内容物としては、医薬品の他、食品、調味料(調味油)、化粧品、入浴剤、雑貨(玩具・接着剤等)など適宜の目的の材料を用いることができる。また、その内包状態(収容状態)としては、液体状の他、ゲル状、粉粒体、あるいは適宜これらを混入した状態、例えば液体中に粉体を混合させた粉体含有懸濁液等とすることが可能である。また以下の説明においては、主に液体状の内容物を収容する場合について説明する。
一方、外皮部は、動物由来のゼラチンを基材とすることが多いが、植物由来の澱粉を主成分とすることも可能である。因みに澱粉を主成分とする場合には、その他にλカラギーナン、金属塩、デキストリン、可塑剤、及び水などが配合される。
First, the seamless capsule C will be described.
The seamless capsule C, for example, contains an oily drug or food in the capsule and is coated with a water-soluble polymer (gelling agent) such as gelatin and is often formed in a substantially spherical shape. In the following description, the seamless capsule C having a substantially spherical shape will be mainly described.
In addition, in the production of the seamless capsule C, as described above, generally, a technique of dripping the chemical solution as the contents from the double nozzle and the outer skin liquid as the outer skin portion into the curing liquid (cooling liquid) at the same time and curing it is generally performed. Many have been adopted (manufactured so-called artificial salmon roe). In this case, as a matter of course, the chemical solution is delivered from the inner portion of the double nozzle, and the outer skin fluid is delivered from the outer portion of the double nozzle.
Then, according to such dripping, for example, by giving vibration to the double nozzle, the liquid delivered from the double nozzle is separated into appropriate sizes one by one (it will be dripped) A seamless capsule C having a substantially uniform size without a seam is obtained.
As described above, the basic structure of the seamless capsule C is formed by covering the contents such as a chemical solution with a seamless outer skin portion. Here, as the contents, appropriate materials such as foods, seasonings (seasoning oils), cosmetics, bathing agents, sundries (toys, adhesives, etc.) can be used in addition to pharmaceuticals. In addition, the encapsulated state (accommodating state) includes a liquid form, a gel form, a granular body, or a state in which these are appropriately mixed, for example, a powder-containing suspension in which powder is mixed in a liquid. Is possible. Moreover, in the following description, the case where the liquid content is mainly accommodated is demonstrated.
On the other hand, the outer skin part is often based on animal-derived gelatin, but it can also be composed mainly of plant-derived starch. Incidentally, in the case where starch is the main component, λ carrageenan, metal salt, dextrin, plasticizer, water and the like are blended.
そして、このようなシームレスカプセルCの製造中、上記の二重ノズルに与える振動の加減や液体の粘性等によっては、本来一つずつに分離されるはずのシームレスカプセルCが連結・固着し、不良となって出現することがある(これを「連球不良品」とし、二つのシームレスカプセルCが連結することが多いが、三つ以上つながったものも含む)。ここで、図中のシームレスカプセルCに付した符号「Cg」は、一個ずつ分離された良品を示し、「Cn」は複数個が連結・付着した不良品(連球不良品)を示している。
このように、本発明における検査対象物はシームレスカプセルCであり、特に以下の実施例では良品の状態で、ほぼ球形状を成すシームレスカプセルCについて主に説明するが、被検査体としてのシームレスカプセルCの形状は、必ずしも球形状に限定されるものではない。
そして、本発明は、エア接触エリアARに、このようなシームレスカプセルCを個々に供給し(落下させ)、エアの力でシームレスカプセルCを吹き飛ばし、その飛距離の差で良品Cgと連球不良品Cnとを選別するものである。
During the manufacture of such a seamless capsule C, the seamless capsule C, which should have been separated one by one, depending on the vibrations applied to the double nozzle and the viscosity of the liquid, is connected and fixed, resulting in a defect. (This is regarded as “Ball-ball defective product”, and two seamless capsules C are often connected, but also include those in which three or more are connected). Here, the symbol “Cg” attached to the seamless capsule C in the figure indicates a non-defective product that is separated one by one, and “Cn” indicates a defective product in which a plurality are connected and adhered (ball-joint defective product). .
As described above, the inspection object in the present invention is the seamless capsule C. In particular, in the following examples, the non-defective state of the seamless capsule C having a substantially spherical shape will be mainly described. The shape of C is not necessarily limited to a spherical shape.
In the present invention, such seamless capsules C are individually supplied (dropped) to the air contact area AR, and the seamless capsules C are blown off by the force of air. The non-defective product Cn is selected.
次に、連球不良品の検出装置1(以下、単に「検出装置1」とする)について説明する。
検出装置1は、上述したように、シームレスカプセルCを製造する際に発生し得る連球不良品Cnを機械的に且つ短時間で、しかも高い精度で良品Cgから選別し、除去する装置であり、検査まで含めたシームレスカプセルCの大量生産に対応するものである。
検出装置1は、一例として図1(a)に示すように、多くのシームレスカプセルCを一時的にストックしながら、後段の整列搬送部3に一定量ずつ送り出す貯留部2と、当該貯留部2から送り出されたシームレスカプセルCを、ほぼ一定の姿勢に規制しながら、一つずつ(個々に)後段の選別部4(エア接触エリアAR)に落下させる整列搬送部3と、当該整列搬送部3から送られたシームレスカプセルCにエアを当てて(吹き付けて)、良品Cgと連球不良品Cnとに選別する選別部4とを具えて成るものである。以下、各構成部について説明する。
Next, a defective ball detecting device 1 (hereinafter simply referred to as “detecting device 1”) will be described.
As described above, the detection device 1 is a device that sorts and removes defective continuous ball Cn that may occur when the seamless capsule C is manufactured from the non-defective product Cg mechanically, in a short time, and with high accuracy. It corresponds to mass production of seamless capsule C including inspection.
As shown in FIG. 1 (a) as an example, the detection apparatus 1 temporarily stores a large number of seamless capsules C, and sends out a predetermined amount to the rear-stage alignment transport unit 3 and the storage unit 2 Aligning and conveying unit 3 for dropping seamless capsules C sent out from each of them into individual sorting unit 4 (air contact area AR) one by one (individually) while restricting to a substantially constant posture; Is provided with a selection unit 4 that applies air (sprays) to the seamless capsules C sent from, and sorts them into non-defective products Cg and defective continuous balls Cn. Hereinafter, each component will be described.
まず貯留部2から説明する。
貯留部2は、上述したように検査を受けるシームレスカプセルCを一旦、貯留する部位であり、貯留部本体としてのホッパー21を主な構成部材とする。
ホッパー21には、大量のシームレスカプセルCがランダムな状態(バラバラの状態)で投入されるが、シームレスカプセルCがホッパー21下部に形成された排出口に至るまでの間に、排出口の構造や、排出口に至る壁面の構造等によって、シームレスカプセルCを少量ずつ、定量的に且つほぼ同じ姿勢で整列搬送部3に送り出す構造となっている。特に、ここでは後述する整列搬送部3が三本の搬送軌道(レール)を有するように形成されるため、シームレスカプセルCも各搬送軌道に一個ずつ載るようにホッパー21から送り出される。
First, the storage unit 2 will be described.
The storage part 2 is a part for temporarily storing the seamless capsule C to be inspected as described above, and the hopper 21 as the storage part main body is a main constituent member.
A large number of seamless capsules C are put into the hopper 21 in a random state (disjoint state), but the structure of the discharge port or the like until the seamless capsule C reaches the discharge port formed below the hopper 21. Depending on the structure of the wall surface leading to the discharge port, etc., the seamless capsule C is sent to the aligning / conveying unit 3 in small amounts and quantitatively in substantially the same posture. In particular, since the alignment conveyance unit 3 described later is formed to have three conveyance tracks (rails), the seamless capsules C are also sent out from the hopper 21 so as to be placed one by one on each conveyance track.
次に整列搬送部3について説明する。
整列搬送部3は、シームレスカプセルCをほぼ同じ姿勢に規制しつつ、一つずつ(個々に)後段の選別部4(エア接触エリアAR)に送り込むものであり、一例として図2に示すように、V溝が切られた搬送軌道としての三本のレール31と、このレール31に振動を加える加振機構(図示略)とを具えて成るものである。
レール31は、移送先端側(つまりエア接触エリアAR)に向けて下り傾斜を有するように形成され、シームレスカプセルCは、このレール31に形成されたV溝によって列状に安定的に載置され(一列に並び)、また加振機構により該レール31に加えられる振動によって、一つずつ(個々に)エア接触エリアARに落下供給されるものである(いわゆる振動コンベヤの形態)。
なお、上記レール31の下り傾斜は、シームレスカプセルCを一列に載せることや、加振機構による振動によってエア接触エリアARに当該カプセルを個別に落下供給すること等を考慮して設定されるものであり、シームレスカプセルCの大きさや比重、あるいは加振機構の振動状況等によっても異なる。もちろんレール31の角度を設定するにあたっては、例えば加振機構の作動を停止した場合に、シームレスカプセルCが自重でレール31から自然落下してしまわないこと等も考慮される。
Next, the alignment transport unit 3 will be described.
The aligning and conveying unit 3 feeds the seamless capsule C to the subsequent sorting unit 4 (air contact area AR) one by one (individually) while restricting the seamless capsule C to substantially the same posture, as shown in FIG. The three rails 31 serving as conveyance tracks with the V-grooves cut off, and an excitation mechanism (not shown) for applying vibration to the rails 31 are provided.
The rail 31 is formed to have a downward slope toward the transfer front end side (that is, the air contact area AR), and the seamless capsule C is stably placed in a row by the V-groove formed in the rail 31. (Arranged in a line) and is supplied to the air contact area AR one by one (individually) by the vibration applied to the rail 31 by the vibration mechanism (in the form of a so-called vibration conveyor).
The downward inclination of the rail 31 is set in consideration of placing the seamless capsules C in a line or individually supplying the capsules to the air contact area AR by vibrations from the vibration mechanism. Yes, it varies depending on the size and specific gravity of the seamless capsule C or the vibration state of the vibration mechanism. Of course, when the angle of the rail 31 is set, for example, when the operation of the vibration mechanism is stopped, it is considered that the seamless capsule C does not naturally fall off the rail 31 due to its own weight.
また、本実施例では上記レール31がエア接触エリアARに向けて下り傾斜を有するように形成されることから、選別部4(エア接触エリアAR)に供給されるシームレスカプセルCは、整列搬送部3から斜め放り出し状態に落下する形態となり、これによりエア接触エリアARにおけるシームレスカプセルCの落下姿勢がほぼ同じ状態に維持される。すなわちシームレスカプセルCは、ほぼ一定の力と傾斜角度でレール31からエア接触エリアARに放り出されるものであり、これにより落下姿勢がほぼ均一化する。
なお、ここではシームレスカプセルC(良品Cg)の形状が球形であるため、上記構成により、特に連球不良品Cnの落下姿勢がほぼ均一に揃えられるものである。すなわち、連球不良品Cnは連結方向が長手方向(長手寸法)となり、このものは落下時、当該長手方向を概ね垂直に向けた縦姿勢や、長手方向を概ね水平に向けた横姿勢等を取ることがあり得るが、上記構成により、長手方向が一定の角度を保ってレール31から落下するようになり、連球不良品Cnにおいてエアを受ける面積が均一化するものである。逆に言えば、連球不良品Cnの場合、落下姿勢が一定していないと、エア接触エリアARでの落下姿勢が縦姿勢と横姿勢とでは、エアを受ける面積が大きく異なり、エアによる飛距離にもバラツキが出ると考えられ(連球不良品Cnが良品Cgに混入することがあり得)、選別の精度に悪影響を及ぼし得るものである。もちろん連球不良品Cnと良品Cgとの飛距離に多少の差が生じても、これが両者の混入を招くほどでなければ何ら構わず、その意味で本明細書や特許請求の範囲においても「ほぼ(同じ姿勢で落下)」と記載したものである。
In the present embodiment, since the rail 31 is formed to have a downward slope toward the air contact area AR, the seamless capsule C supplied to the sorting unit 4 (air contact area AR) 3 is dropped into an obliquely projecting state, whereby the dropping posture of the seamless capsule C in the air contact area AR is maintained in substantially the same state. That is, the seamless capsule C is ejected from the rail 31 to the air contact area AR with a substantially constant force and an inclination angle, and thereby the dropping posture is substantially uniform.
Here, since the shape of the seamless capsule C (non-defective product Cg) is a sphere, the falling posture of the continuous ball defective product Cn can be made substantially uniform by the above configuration. That is, the connected ball defective product Cn has a longitudinal direction (longitudinal dimension) in the connecting direction, and when dropped, this product has a vertical attitude in which the longitudinal direction is substantially vertical, a horizontal attitude in which the longitudinal direction is substantially horizontal, and the like. Although it may take, the said structure will fall from the rail 31 maintaining a fixed angle in a longitudinal direction, and the area which receives air in the continuous ball defective article Cn becomes uniform. In other words, in the case of the defective ball Cn, if the dropping posture is not constant, the falling posture in the air contact area AR is greatly different between the vertical posture and the horizontal posture, and the flying by the air It is considered that the distance also varies (the ball-joint defective product Cn may be mixed into the non-defective product Cg), which may adversely affect the sorting accuracy. Of course, even if there is a slight difference in the flight distance between the defective ball Cn and the non-defective Cg, it does not matter as long as this does not cause the mixing of both. "Almost (falling in the same posture)".
次に選別部4について説明する。
選別部4は、エア接触エリアARに個々に供給される(本実施例では分散状態で落下供給される)シームレスカプセルCを良品Cgと連球不良品Cnとに仕分ける部位であり、整列搬送部3(レール31)からエア接触エリアARに落下してくるシームレスカプセルCにエアを吹き付けるためのエア噴出ノズル41を主な構成部材とする。
ここで当該エア噴出ノズル41から噴出されるエアは、シームレスカプセルCの落下方向と交差する方向に指向させるものであり、本実施例ではレール31の傾斜にほぼ沿って斜め下方に落下してくるシームレスカプセルCに対し、ほぼ水平にエアを当てるようにしている。
また、本実施例では、エア吹き付けによるシームレスカプセルCの飛距離の差によって良品Cgと不良品Cnとの選別を行っており、具体的には複数のカプセルが連結して比較的重量が嵩む連球不良品Cnを遠くに飛ばし、カプセル同士の連結固着が無く連球不良品Cnよりも軽くなる良品Cgを近くに飛ばして選別するものであり、この点が極めて画期的である。すなわち通常の風選は、軽い被検査体を遠くに飛ばし、重い被検査体を近くに飛ばして選別しており、この点が相違する。
また、良品Cgの数量が連球不良品Cnよりも圧倒的に多いこと等から、本実施例では、良品収容部42として比較的容量の大きい容器(ここでは広いトレー状のもの)を使用し、不良品収容部43として比較的容量の小さい容器(ここでは小さなボックス状のもの)を使用し、エア接触エリアARの近くに飛ぶ良品Cgと、遠くに飛ぶ連球不良品Cnとを別々に回収している。
Next, the sorting unit 4 will be described.
The sorting unit 4 is a part that sorts the seamless capsules C individually supplied to the air contact area AR (dropped and supplied in a distributed state in this embodiment) into a non-defective product Cg and a continuous ball defective product Cn. 3 is an air jet nozzle 41 for blowing air onto the seamless capsule C falling from the 3 (rail 31) to the air contact area AR.
Here, the air ejected from the air ejection nozzle 41 is directed in a direction intersecting with the falling direction of the seamless capsule C, and in the present embodiment, the air drops obliquely downward substantially along the inclination of the rail 31. Air is applied substantially horizontally to the seamless capsule C.
Further, in this embodiment, the non-defective product Cg and the defective product Cn are selected based on the difference in the flying distance of the seamless capsules C by air blowing. Specifically, a plurality of capsules are connected to each other so that they are relatively heavy. The defective ball product Cn is skipped far away, and the good product Cg which is lighter than the continuous ball defective product Cn without connection and fixation between the capsules is skipped and selected. This point is extremely epoch-making. That is, in the normal wind selection, a light object to be inspected is distant and a heavy object to be inspected is selected.
In addition, since the quantity of the non-defective product Cg is overwhelmingly larger than the defective continuous ball Cn, in this embodiment, a container having a relatively large capacity (in this case, a wide tray-like shape) is used as the non-defective product containing portion 42. A defective container (in this case, a small box-shaped container) is used as the defective product receiving portion 43, and a non-defective product Cg flying near the air contact area AR and a defective continuous ball product Cn flying far are separated. Collected.
またシームレスカプセルCにエアを当てるにあたっては、一例として図1(b)に示すように、整列搬送部3(レール31)における移送先端下部にまずエアを当てて、エアの方向(指向)をほぼ水平方向に補正した状態で、エア接触エリアARを落下中のシームレスカプセルCに当てるようにしており、レール31の移送先端下部において上記作用を担う部位をエア指向補正部44とする。
これにより、ほぼ同じ姿勢で落下してくるシームレスカプセルCへのエアの吹き付け方向(指向)が一定となり(ここではほぼ水平)、良品Cgと連球不良品Cnとにおいて飛距離の差をより明確に生じさせることができ、より一層、風選の精度を向上させることができる。
Further, when air is applied to the seamless capsule C, as shown in FIG. 1B as an example, air is first applied to the lower part of the transfer tip in the alignment transport unit 3 (rail 31), and the air direction (direction) is substantially set. The air contact area AR is applied to the falling seamless capsule C in a state corrected in the horizontal direction.
As a result, the air blowing direction (orientation) to the seamless capsule C falling in almost the same posture becomes constant (here, almost horizontal), and the difference in flight distance between the non-defective Cg and the defective ball Cn is clearer. The accuracy of wind selection can be further improved.
因みに、重い連球不良品Cnの方が、軽い良品Cgよりも遠くに飛ぶのは(飛距離が長いのは)、連球不良品Cnは、複数個つながったカプセルのうち最初にエアを受けたカプルセル(球)が吹き飛ばされると、エアを受けていないカプルセル(球)を中心として連球不良品Cn全体が回転するようになり(いわゆる遠心力)、今度は当初エアの吹き飛ばし作用を受けていなかったカプセル(球)が、エアの吹き飛ばし作用を受け、更に回転力が増すという、回転を伴った吹き飛ばしが順次繰り返されるため、球形状を成す良品Cgよりも遠くに飛ぶと考えられる。換言すれば、良品Cgは、ほぼ球形状を成すために、エアによる吹き飛ばしを受けても、これがシームレスカプルセルC(良品Cg)全体を回転させる遠心力にはならず(遠心力は伴わず)、飛距離も伸びないと考えられる。もちろん、連球不良品Cnは、カプセルが複数個つながっている分、エアを受ける面積が大きくなり、このことも飛距離が長いことの一要因と考えられる。   By the way, the heavier defective ball Cn flies farther than the lighter non-defective Cg (has a longer flight distance), but the defective ball Cn receives air first among a plurality of connected capsules. When the couple cell (ball) is blown off, the entire continuous ball defective product Cn rotates around the couple cell (sphere) that has not received air (so-called centrifugal force), and this time it is initially subjected to air blowing action. The capsules (spheres) that did not exist are subjected to the air blowing action, and the blowing force accompanied by the rotation, which further increases the rotational force, is repeated in sequence, so it is considered that the capsules (spheres) fly farther than the non-defective Cg having a spherical shape. In other words, since the non-defective product Cg has a substantially spherical shape, even if it is blown off by air, it does not become a centrifugal force that rotates the entire seamless couple cell C (non-defective product Cg) (without centrifugal force). It is thought that the flight distance does not increase. Of course, the defective ball Cn has a larger area for receiving air as a result of the connection of a plurality of capsules, which is also considered to be a factor in the long flight distance.
また、シームレスカプセルCの良品Cgの形状が球形状ではなく、例えば図3(a)に示すように、紡錘状(楕円体)である場合には、良品Cgであっても落下姿勢によってエアが吹き付けられる面積(エアの吹き飛ばし作用を受ける投影面積)が異なると考えられる。すなわち、例えば図3(b)に示すように、長手方向をほぼ垂直に向けた縦姿勢で落下した場合には、エアを受ける投影面積が長円形となるため比較的広くなり、遠くに飛び易いと考えられる。一方、長手方向をほぼ水平に向けた横姿勢で落下した場合にはエアを受ける投影面積が円形となるため比較的狭くなり、近くに飛び易いと考えられる。もちろん縦姿勢で落下した場合には、回転力(遠心力)も加わり易く、横姿勢で落下するシームレスカプセルCとは飛距離の差が生じ易い(同じ良品Cgであってもバラツキが出易い)と考えられる。
従って、シームレスカプセルC(良品Cg)の形状が紡錘状であるような場合、換言すれば、いずれかの方向から視たシームレスカプセルCの投影面積が異なる形状の場合には、良品Cgそのものからして落下姿勢を積極的に揃えることが好ましいと考えられる。なお、ほぼ球形状を成すシームレスカプセルCは、全方向から視た投影面積がほぼ同じと言える。
Further, when the shape of the non-defective product Cg of the seamless capsule C is not spherical, but is, for example, a spindle shape (ellipsoid) as shown in FIG. It is considered that the areas to be sprayed (projected areas that receive air blowing action) are different. That is, for example, as shown in FIG. 3B, when the projector is dropped in a vertical posture in which the longitudinal direction is substantially vertical, the projection area that receives air becomes an oblong shape, so that it is relatively wide and easily fly away. it is conceivable that. On the other hand, when falling in a horizontal posture with the longitudinal direction substantially horizontal, the projected area for receiving air becomes circular, so it is relatively narrow and is likely to fly close. Of course, when falling in a vertical posture, a rotational force (centrifugal force) is also easily applied, and a difference in flight distance is likely to occur with the seamless capsule C falling in a horizontal posture (even if the same non-defective Cg is easily generated). it is conceivable that.
Accordingly, when the shape of the seamless capsule C (non-defective product Cg) is a spindle shape, in other words, when the seamless capsule C has a different projected area as viewed from any direction, the non-defective product Cg itself is used. Therefore, it is considered preferable to positively align the falling posture. In addition, it can be said that the seamless capsule C having a substantially spherical shape has substantially the same projected area when viewed from all directions.
また、上記説明では、基本的にレール31の傾斜と加振機構の振動とにより、レール31上に載置したシームレスカプセルCをエア接触エリアARに向けて移送するようにしており、レール31上においてシームレスカプセルCを回転させながら(自転させながら)移送するものではない。これは、連球不良品Cnが回転(自転)しないためであるが、良品Cgのみレール31上を回転(自転)させながら、移送するようにしても構わない。   In the above description, the seamless capsule C placed on the rail 31 is basically transferred toward the air contact area AR by the inclination of the rail 31 and the vibration of the vibration mechanism. The seamless capsule C is not transferred while rotating (rotating). This is because the defective ball Cn does not rotate (spin), but only the non-defective product Cg may be transported while rotating (spinning) on the rail 31.
また上記説明では、シームレスカプセルCをレール31から放出してから、端的にはシームレスカプセルCがレール31から離脱してからエアを吹き付けるものであったが、本発明は必ずしもこれに限定されるものではない。すなわち、例えば図4に示すように、シームレスカプセルCが載るレール31にエア噴出孔31hを形成しておき、シームレスカプセルC(良品Cg)がレール31上にあるうちにエアを吹き付け、ここからシームレスカプセルCを飛ばすことも可能である。ここでエア噴出孔31hは、シームレスカプセルC(良品Cg)一個分に作用させるものとする。
このような構成でも、シームレスカプセルCは、レール31上(整列搬送部3上)にあるため同じ姿勢をとった状態でエアが吹き付けられ、しかも個々のシームレスカプセルCにエアを当てることができるものである。なお、この場合には、エア接触エリアARは、レール31上におけるエア噴出孔31hが形成された部位となる。
また、特許請求の範囲(請求項1、5)において「個々に(落下させる)」と記載したのは(「分散状態(で落下させる)」と記載しなかったのは)、上記のようにレール31上に列状に並んだカプセルを一つずつ吹き飛ばす形態も包含するためである(レール31上に列状に並んだシームレスカプセルCの状態を「分散」表現に含めるのは、そぐわないと考えたためである)。
In the above description, the seamless capsule C is discharged from the rail 31, and then the air is blown after the seamless capsule C is detached from the rail 31, but the present invention is not necessarily limited to this. is not. That is, for example, as shown in FIG. 4, air ejection holes 31h are formed in the rail 31 on which the seamless capsule C is placed, and air is blown while the seamless capsule C (non-defective product Cg) is on the rail 31. It is also possible to skip the capsule C. Here, the air ejection hole 31h is assumed to act on one seamless capsule C (non-defective Cg).
Even in such a configuration, since the seamless capsule C is on the rail 31 (on the alignment conveyance unit 3), air can be blown in the same posture, and air can be applied to each seamless capsule C. It is. In this case, the air contact area AR is a portion where the air ejection holes 31h on the rail 31 are formed.
Further, in the claims (Claims 1 and 5), “individually (dropped)” is described (not described as “distributed state (dropped)”) as described above. This is because the capsules arranged in a row on the rails 31 are blown one by one (including the state of the seamless capsules C arranged in a row on the rails 31 in the “distributed” expression is not appropriate. Because)
因みに、上記図4の場合には、シームレスカプセルCの比重、エアの噴出量、エアの噴出方向(最終的にシームレスカプセルCに作用する向き)等により、連球不良品Cnが良品Cgよりも遠くに飛ぶとは限らないが(つまり連球不良品Cnが良品Cgよりも近くに着地するかも知れないが)、良品Cgと連球不良品Cnとにおいて飛距離の差を生じさせることは可能であり、従ってこのような形態でも連球不良品Cnを選別することができる。
このように、本発明では、シームレスカプセルCが必ずしもレール31(整列搬送部3)から離れた状態(放り出された状態)でエアの吹き付けを行う必要はないものである。
Incidentally, in the case of FIG. 4 above, due to the specific gravity of the seamless capsule C, the air ejection amount, the air ejection direction (direction that finally acts on the seamless capsule C), etc., the defective continuous ball Cn is more than the non-defective product Cg. Although it does not always fly far (that is, the defective ball Cn may land closer to the non-defective Cg), it is possible to cause a difference in flight distance between the non-defective Cg and the defective ball Cn. Therefore, the defective continuous ball Cn can be selected even in such a form.
Thus, in the present invention, it is not always necessary to blow air in a state in which the seamless capsule C is separated from the rail 31 (alignment transport unit 3) (a state in which the seamless capsule C is released).
